Cryptocurrency is a type of digital or virtual money based on cryptography and usually operates in a decentralized manner, without reliance on financial institutions or governments. The most well-known and first cryptocurrency is Bitcoin, introduced in 2009 by a person or group under the pseudonym Satoshi Nakamoto.
Key Features of Cryptocurrencies:
1. Decentralization: Most cryptocurrencies use a network called Blockchain, which is not controlled by any single authority.
2. High Security: Due to strong encryption, transactions are traceable but nearly impossible to hack.
3. Transparency: All transactions are recorded in a public ledger (blockchain) and can be viewed by anyone.
4. Relative Anonymity: Personal user data is usually not directly recorded. Some coins like Monero or Zcash offer full anonymity.
